I see you have a chest rest, but I would want it further forward and I would add a chin rest for your helmet.

Tom, I would argue against having your helmet touching any part of the bike, even on a pad.... your eyes don't need the vibration

Hi,

I made the pad so to look like the original pad, but I won't probably use it at Speed Week!!!

Also hit small problem... Was about to fit the last screw on the bike, the pressure regulating one (ball/spring/screw), and guess what, it's the only thread I did not check, and yes, it's slightly chewed up...

So ordered the tap, VERY COMMON, 7/16th by 26 TPI, NOT UNF, NOT Whitworth, Cycle???, might get it via the postman tomorrow!!!

Wish me luck!

So instead, worked on my 78 iron head XLH Sportster, it was feeling a touch lonely lately..........

You make that tank pad as thick and soft as possible.  If I did not have them (on three record holding bikes), I would not be able to hold my head up. Like this:

I'm no biker, so this may be a naive question: how do you see where you are going in the bottom picture?

I look thru the front window! This is the same bike as the fully faired version above on which I do the same thing.

From the side view it looks like the top of the helmet prevents you seeing forwards over the tank. Depends where your eyes are I suppose. Don't tell me, they are on the front of your head (just below the eyebrows) like everyone else.  8-)  :roll:

The other advantage of the tank pad, with your helmet strapped on tightly (which is the only safe way), is that the pad forces your helmet up just enough to allow maximum forward vision thru the upper extremity of the eye port in the helmet. I believe that Shoei is now making a helmet for racing with a higher eye port just for this reason.

Sorry, Patrick, for the hijacking of your thread.

That is a Shoed X-14.  You can buy internal pads of different thicknesses.  Thick front pads and thin back ones make the helmet sit higher in the front and this improves the view.  The X-14 alone had better aero in the wind tunnel than the X-14 with a speed hump on the leathers.
